min activities in a building

[Liviu Lalescu]

I thank you for your understanding, and I will now begin the change. The name of the constraint will be changed, but the behavior will remain the same, only with +1. The old files will be opened and updated correctly - no need from the user to do anything.

[Benahmed Abdelkrim]

Thank you dear Liviu. Let me know when it's ready

[Liviu Lalescu]

I estimate in a few hours. I'll write here.

[Liviu Lalescu]

Dear Benahmed, it is ready (I had to do also some other suggestion).

https://lalescu.ro/liviu/fet/download/test/

Please check and let me know if you like it!

To translate, prefer: https://lalescu.ro/liviu/Backup-fet/ (I might change some fields sooner than on 'test').

Edit: could you please compare on some files, the seeds for official-7.8.1 should be the same at the end as 7.8.2-snapshot (if you also start with the same seed; respectively, for each file)?

Changing the name could generalize the application of this constraint and no longer limit it to exams only, This is interesting ... I think

I agree. I think in this form the constraint can be useful in other situations. I will test it in my school's timetable, where we have 2/3/4 subject rooms in which distribute the teacher's hours.

[Benahmed Abdelkrim]

I just see it. I will download, translate, test, and let you know ...

[Benahmed Abdelkrim]

By the way, our constraint can be used in more general cases; a simple name change changed everything... I wonder why we didn't notice this sooner?!

[YOUSSEF HOUIET]

This is because we focused on applying this constraint only to exam-related cases.
However, it could also be useful in more general scenarios. In the future, the constraint could be generalized to apply to a  set of activities, defined through criteria such as a specific teacher, activity tag, subject,...

I tested it with 3 files; the seeds after are the same...

Please check and let me know if you like it!

The new name seems nicer and clearer now...

[Liviu Lalescu]

Great! Thank you, flauta, Benahmed, and YOUSSEF!

I added YOUSSEF's suggestion in the TODO list. We'll see.

[Liviu Lalescu]

Dear Benahmed and maybe YOUSSEF,

Should we consider to make the new constraint "room(s) max activities per teacher" consider that an activity with two or more teachers will count, as well? Now, only activities with a single teacher are considered, because all activities in Benahmed's examples had a single teacher and because it was (much?) easier.

[YOUSSEF HOUIET]

In its current use, the constraint is applied only to activities with a single teacher. I do not think it is necessary to extend it to activities involving two or more teachers.

No, let's leave things as they are. This constraint applies to each room (let's remember, 2 or 3 activities) concerns the buildings, not the rooms...

I just finished the translation. I sent you an email. please check
